SPECIFICATION forming part of Letters Patent No. 526,162, dated September 18, 1894 Application filed November 13, 1893.

To all whom it may concern:

Be it known that I, ALBERT A. PAGE, of East Haven, in the county of New Haven and State of Connecticuhhave invented a new 5 Improvement in Spring-Hinges, (Case 13;) and I do hereby declare the following, when taken in connection with accompanying drawlngs and the letters of reference marked thereon, to be a full,clear, and exact-descrip- IO tion of the same, and. which said drawings] constitute part of this specification, and represent, in l r Figure 1, a view in front elevation ofa spring-hinge constructed in accordancewith 15 my lnvention; Fig. 2, a rear view thereof; Fig. 3, a front View of the hinge with its spring barrel in vertical section. a My invention relates to an improvementin spring-hinges for doors, the object being to produce at a low cost for manufacture a simpie, strong and efiective article, not liable to disfigurement in use by the buckling of the the spring, due to coiling the same in the wrong direction.

2 With these ends in view, my invention consistsin aspring-hinge having one of its leaves constructed upon its inner edge with a long integral spring-chamber or barrel, and with one or more knuckles located in line therew th, a leaf constructed upon its inner edge with one or more knuckles arranged to coactwit-h the knuckles of the chambered leaf, a pintle passing through the knuckles, a spring located in the said chamber and connected therewith at one end thereof, and an ad usting head located in the otherend of the chamber, and havingthe opposite end of the spring connected with it, and carrying a pmfwhich normally engages with the other 0 ea 4 My invention further consists in certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.

In carrying out my invention, I cast a long barrel or cylindrical chamber A, integral with the inner edge of the leaf A of the hinge, the said leaf being alsoconstructed with two knuckles A and A located in line with the barrel, and centrally perforated to receive the pintle B, which also passes through the knuc- Se'rial No. 490.746. (llo model.)

kles O and O of the other leaf 0 of the hinge.

The leaf A is made long so as to provide a support for the lower end of the spring-chamber A. No such necessity, however, exists 5 for making the other leaf 0 long, and it may be made long or short. Preferably it will be made short as that construction is the most compact and lightest, and requires the least material, and reduces the cut made to receive it in the door or door-jamb, to obvious advantage. Within the chamber 'A,'I locate a heavy spiral spring D, secured at its lower end to a plug E,insertedinto the lower i end of the barrel, and secured therein by means of a pin e, whereby the lower end of the springis rigidly connected Withtheohambered leaf A of the hinge.

The opposite or upper end'of the spring is attached to a rotatable adj listing-head F, 10- 7o cated in the upper end of the barrel, having rotatable bearing thereon,and held in place by the projecting inner end of the pintle, as

shown in Fig. 3. The exposed edge of the said head is furnished with a number of radial sockets f, adapted to receive the pin G,

by means of which the power of the spring is exerted upon the leaf 0 of the hinge, as clearly shown in Fig. 2 of the drawings, the said leaf being constructed near its lower end So with a shoulder c, for engagement by the pin. lhe sockets F. in the head open not only into the periphery thereof, but also into the upper face thereof, this construction enabling the heads to be cast and the sockets cored out, whereby an economy is secured over casting the head and boring the sockets in it. Forthe purpose of adjusting the tension of the spring, a wire or long heavy pin is inserted into one of the unoccupied sockets f of the adjusting head F, and the same turned in one direction or the other. Then when the pin G is disengaged from the shoulder a, it may be removed from the head, and inserted into oneof the other sockets thereof. In case the 5 spring is wound in the wrong direction, which may-be done within narrow limits, the pin will engage with the opposite point on the leaf A, whereby its action will be neutralized, for then its tension will be exerted solely roo upon the same leaf of the hinge, and the leaf G thereof will swing as though the hinge the knuckles of the hinge, I am enabled to,

secure ample room for the free action of the spring, to obvious advantage. The gain by making one leaf short, has already been referred to.

It is apparent that both of the leaves of the hinge may be modified in size, and form, if desired, and that the particular devices employed for holding the spring in place and adjusting it may also be varied, and I would therefore have itunderstood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations therein as fairly fall within the spirit and scope of my invention.

I am aware that it is old, broadly speaking to house or inclose a hinge spring inasmuch as the same have been, located within tubular pintles. I am also aware that it is old to locate the spring of a hinge in line with its knuckles and connect its opposite ends with the respective hinge leaves. I am further aware that it is old to provide a spring-hinge with a rotatable adj usting-head provided with radial sockets. I do not, therefore, claim any of those constructions broadly.

I am aware that it is old to locate a cylin- 4o drical chamber in line with the knuckles of the leaf of a hinge, and to place a spring and otherinstrumentalities within the said chamber and I do not, therefore, broadly claim the location of a chamber in line with the knuckles of a hinge leaf.

Having fullydescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a spring hinge, the combination with a hinge-leaf, having a spring chamber or barrel and one or more knuckles cast integral with its body, the said barrel or chamber being made open at both ends and the said knuckle or knuckles being located at one end of the said barrel or chamberand separated therefrom by a space, of a leaf constructed upon the inner edge of its body with one or more knuckles arranged to coact with the knuckle orknuckles of the chambered leaf, a pintle passing through the knuckles but not through the spring-chamber, a spring located in the said chamber and connected, therewith at the outer end thereof, through which it is introduced thereinto, and an adjusting head 5 located in the space formed in the chambered leaf, as described, and having the inner end of the spring connected with it and carryinga pin, which normally engages with the other leaf, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ALBERT A. PAGE.
